C++ grpc callback sevrer cpu usage

[Aleh Linkin]

Hi, everyone.

I have grpc callback server and try to send about 1500 unary ping-pongs per second and I get about 170% CPU usage on server with 32 CPU.

I'd like to understand is it ok because of 16th threads are used by callback server or I do something incorrectly?

Thank you.

170% CPU usage on 32 cores shouldn't be a lot. Using typical load metrics, this is about 5% per core. The load reporting for "all of the computing power is being used at max capacity" should be 3200% in your case. Of course it depends on your reporting tool.
